In January 2026, Shortwave announced its Tasklet integration — an AI agent layer that automates multi-step email workflows entirely without human intervention. That update crystallized what the app has been building toward since 2022: not just a prettier Gmail interface, but a Gmail client where AI handles the actual work. I ran Shortwave as my primary Gmail client for two weeks across Mac, iOS, and Android to find out whether the AI features hold up to daily scrutiny — or whether “AI-first email” is still mostly marketing. The short answer: the AI is real, the Gmail-only constraint is a genuine limitation, and the pricing is steep enough that you need to know exactly who it is for.
TL;DR — Verdict at a Glance
Shortwave is the deepest AI integration currently available in a Gmail client. AI Summaries, AI Search, AI Assistant, AI-powered Bundles, AI Filters, and MCP integrations with Slack, Notion, Asana, and HubSpot are all included in the paid plans — not add-ons. Gmail-only, cross-platform (Mac, iOS, Android, Windows, web), no free tier. Business starts at $24/month/seat. The closest thing to the spiritual successor of Inbox by Gmail, rebuilt for the AI era.
Best for: Gmail-heavy teams and solo professionals who want AI to automate triage, search across years of history, summarize long threads, and write in their voice — and who live entirely within Gmail. Also the natural home for Inbox by Gmail veterans who want that same “zero friction” ethos with AI replacing the manual work.
Skip if: You have any non-Gmail accounts (Outlook, IMAP, Exchange, iCloud) — Shortwave does not support them. You need a permanent free tier. You are a solo user who finds $24/month hard to justify. You want keyboard-speed-first email over AI-automation-first.
Pricing summary: No free tier. 14-day free trial on all plans. Business $24/month/seat (billed annually), Premier $36/month/seat, Max $100/month/seat. Enterprise available at custom pricing.
Setup and Gmail Onboarding
Shortwave connects exclusively via the Gmail API — OAuth login takes under two minutes, and the inbox populates immediately without a local index rebuild. On Business and Premier, AI Search covers years of your Gmail history from the first day. The tradeoff: if you have any non-Gmail account, the onboarding ends here.
The Gmail-API architecture is what makes Shortwave possible. Unlike IMAP clients that download messages to a local store, Shortwave reads your Gmail data in real time via the API, which means labels, categories, send-as aliases, and thread structure work exactly as they do in Gmail on the web. It also means AI Search can query your entire Gmail history server-side rather than being limited to what has been downloaded locally.
Setup across devices is straightforward. I linked my Gmail account once on Mac and the iOS and Android apps picked up the same account and settings on first launch. Thread sorting preferences, Bundles configuration, and AI filter rules sync across platforms without manual intervention.
One practical note: Shortwave is available as a desktop app on both Mac and Windows — not a web wrapper, but an Electron-based app. The Mac version feels native enough; the Windows version launched after Android (post-August 2023) and covers the cross-platform picture that rival AI clients like Mimestream do not.
If your email world is Gmail only and you work across multiple devices including Android or Windows, setup friction is essentially zero. If you have a company Outlook account alongside your Gmail — Shortwave is not the answer.
Design and Daily Feel
Shortwave’s design philosophy descends directly from Inbox by Gmail — calm visual hierarchy, conversation threading, bundled categories for newsletters and promotions, and a focus on getting to inbox zero without friction. In 2026 the aesthetic has been updated to feel AI-native: AI summaries sit at the top of every thread, the Split Inbox divides your view by importance or custom query, and the overall palette is clean without being sparse.
The default view is a split inbox: pinned important threads above the fold, everything else below. AI assigns priority based on sender history, thread activity, and content — not just a simple rule. After two weeks it was more accurate than I expected, surfacing about 90% of what I’d have pinned manually and correctly deprioritizing newsletters and automated alerts.
Bundles are Shortwave’s answer to Gmail’s Categories tab, but more configurable. You define what goes into each bundle (newsletters from specific domains, GitHub notifications, invoices), and Shortwave surfaces them as collapsed rows you can bulk-triage. For an inbox receiving 100+ emails per day — mine during the test — Bundles compressed the triage work by roughly half.
The keyboard shortcut set covers all standard Gmail actions (archive, snooze, reply, forward, label) and adds Shortwave-specific shortcuts for assigning threads to teammates, creating AI drafts, and triggering AI Search. The shortcut density is lower than Superhuman, which is keyboard-speed-first, but higher than Spark.
On mobile — both iOS and Android — the experience is compressed but complete. AI summaries appear on the thread list as one-line previews, snooze is a swipe action, and Bundles collapse correctly on smaller screens. The Android app received praise in The Verge’s 2023 review for matching the iOS polish, and in my testing it holds up.
AI Features: Summary, Search, Assistant, Bundles
Shortwave shipped 96 features and merged 5,281 pull requests in 2024 alone, per its year-in-review post — the majority AI-related. In 2026 the AI feature set is the broadest of any Gmail client I have tested: AI Summary on every thread, natural-language AI Search across full history, an AI Assistant for complex tasks, AI Write that learns your voice, AI Filters in plain English, AI Autocomplete, AI Scheduling, and in May 2025, MCP-based integrations with external tools.
AI Summary appears at the top of every thread — a two-to-four sentence digest of the conversation, key decisions, and any action items. After two weeks I stopped opening long threads cold; I read the summary first and opened the thread only when I needed context. The quality was consistently good on English threads; French and German threads were summarized accurately but occasionally missed idiom-level nuance.
AI Search is the feature I found most differentiated. Where Gmail’s search requires you to know the right keywords, Shortwave’s AI Search accepts natural language — “the email where the investor mentioned cap table” retrieves the right thread on the first try. On the Business plan this covers 5 years of history; on Premier, unlimited. In my testing, retrieval accuracy was high enough that I stopped using Gmail’s own search interface.
AI Assistant handles multi-step tasks via a chat interface: “Draft a polite follow-up to the three emails where I haven’t heard back in two weeks and send them for my review.” The assistant pulls the relevant threads, drafts the replies, and queues them in your Drafts folder for approval. In January 2026, this was extended via Tasklet integration, which can run AI automations on a schedule or trigger without manual prompting.
AI Write learns your voice from your sent-mail history and generates drafts that match your typical tone, sentence length, and sign-off style. In my testing the drafts were a closer match to my writing than generic LLM drafts — the personalization is real, not cosmetic. AI Autocomplete extends this to inline suggestions as you type.
AI Filters let you write inbox rules in plain English: “Archive all newsletters that don’t mention a product I’ve expressed interest in” — Shortwave converts this into an active filter. The Business plan allows 3 AI filters; Premier allows 10; Max allows 50.
MCP Integrations (launched May 2025) connect Shortwave’s AI to external tools — Slack, Calendar, Notion, Asana, and HubSpot. The assistant can pull context from a Notion doc while drafting a reply, or log an email thread directly to HubSpot. This is the feature that moves Shortwave from email client toward AI-native workflow hub.

Pricing — Business, Premier, Max
Shortwave has no permanent free tier as of 2026. All plans offer a 14-day trial. Business is $24/month/seat (billed annually) with standard AI and 5 years of search history. Premier is $36/month/seat with expanded AI usage, unlimited search history, and 10 AI filters. Max is $100/month/seat with advanced model access, 50 AI filters, and live 1:1 training.
| Plan | Price | AI model | AI Search history | AI filters | AI requests/day |
|---|---|---|---|---|---|
| Business | $24/mo/seat | Standard | 5 years, 50 threads/query | 3 | 150-300 |
| Premier | $36/mo/seat | Advanced (2x context) | Unlimited, 100 threads/query | 10 | ~2x Business |
| Max | $100/mo/seat | Expert (3x context) | Unlimited, 150 threads/query | 50 | ~6x Business |
| Enterprise | Custom | Custom | Custom | Custom | Custom |
The pricing math is meaningful. For a solo professional, Premier at $36/month is $432/year — close to what Superhuman charges and materially above Spark’s $59.88/year. The justification is that the AI features replace work you would otherwise do manually or pay for in separate tools. For teams, the Business plan at $24/seat with email assignment, shared labels, team comments, and shared prompt templates starts to look more like a lightweight CRM layer than just an email client.
One structural note: Shortwave explicitly names the underlying AI model tier (standard / advanced / expert) but as of May 2026 does not publicly document which model family powers each tier. Pricing per plan is annual; monthly billing options exist but specific monthly rates are not prominently displayed on the pricing page.
Compared to the field: Gmail with Workspace Business Standard runs $12/user/month and includes Gemini in Gmail, which covers AI drafting and basic search summarization. Shortwave’s AI goes materially deeper — AI Filters, AI Bundles, AI Scheduling, and MCP integrations are not available in Gemini in Gmail. Whether that depth justifies the delta depends on how AI-automated your workflow actually is.
Shortwave vs Mimestream, Superhuman, Spark, Gmail+Gemini
Shortwave’s competitive position in 2026 is “deepest AI integration in a Gmail-only client.” Mimestream wins on native Gmail fidelity without AI overhead. Superhuman wins on keyboard speed. Spark wins on multi-provider and team features at a lower price. Gmail+Gemini wins on price (it’s the free baseline). Shortwave wins when AI automation depth — Bundles, AI Search, AI Filters, MCP integrations — is the priority.
| Dimension | Shortwave | Mimestream | Superhuman | Spark | Gmail + Gemini |
|---|---|---|---|---|---|
| Gmail-only | Yes | Yes | Yes | No (multi-provider) | Yes |
| Platforms | Mac, iOS, Android, Windows, Web | Mac, iOS | Mac, iOS, Web | Mac, iOS, Windows, Android | Web, iOS, Android |
| Free tier | No (14-day trial) | No (trial) | No | Yes | Yes |
| Paid entry | $24/mo/seat | $49.99/yr | ~$30/mo | $4.99/mo | $12/mo (Workspace) |
| AI Summary | Yes (all threads) | No | No | Basic | Yes (Gemini) |
| AI Search | Yes (natural language) | No (Gmail API only) | No | No | Basic |
| AI Filters | Yes (plain English) | No | No | No | No |
| MCP integrations | Yes (May 2025) | No | No | No | No |
| Team collaboration | Yes (assign, share, comment) | No | Limited | Yes (shared inbox) | Limited |
| Windows desktop app | Yes | No | No | Yes | Web only |
| Android app | Yes | No | No | Yes | Yes |
The Inbox by Gmail lineage point: Google Inbox launched in 2014 and shut down in 2019. It introduced Bundles (now a Shortwave staple), swipe-to-snooze, and a visual thread-pinning model that influenced almost every AI email client that followed. Andrew Lee and Jonny Dimond built on that foundation at Shortwave — the Bundle concept, the emphasis on calm triage, and the “get to zero and stay there” ethos are all direct descendants. If you mourned Inbox’s shutdown, Shortwave is the most direct continuation available.
Shortwave vs Gmail + Gemini deserves a direct comparison. Gemini in Gmail is free with Workspace Business Standard and covers drafting, thread summarization (via the Summarize button), and Help Me Write suggestions. Shortwave’s AI goes further: AI Filters that work in plain English, AI Search across unlimited history, AI Bundles with custom rules, MCP connections to external tools, and Tasklet-level automation. For a solo user who already pays for Workspace, the question is whether that depth gap is worth $24-36/month on top of Workspace. For high-volume inboxes and team use, frequently yes.

Where Shortwave Falls Short
The honest negatives, based on two weeks of daily use and publicly available user feedback:
- Gmail-only is a hard wall. If your work uses Microsoft 365, your company runs Exchange, or you have a personal iCloud mail address — Shortwave cannot touch those accounts. This rules out a meaningful share of professionals who exist in hybrid Gmail + Microsoft environments.
- No permanent free tier. Solo users and freelancers who want AI email benefits but cannot commit $24/month face a dead end after the 14-day trial. Spark, Gmail+Gemini, and even EM Client all have free options.
- AI request limits are real at Business tier. 150-300 daily AI requests sounds like a lot until you have AI Summary enabled on every thread and AI Autocomplete running as you type. Heavy users may feel the ceiling on the $24/month plan.
- Pricing is fully annual. Monthly billing exists but specific rates are not published on the pricing page, which creates friction for teams that evaluate on monthly budgets.
- No PGP or S/MIME support. If email encryption is a requirement, Shortwave is not the answer — Canary Mail or Thunderbird are more appropriate.
- Tasklet and MCP integrations are still new. The Tasklet integration launched in January 2026; MCP integrations in May 2025. Both are powerful on paper but have the rough edges of recently shipped features — limited documentation and occasional unexpected behavior in complex automations.
- No Outlook import or migration tool. Teams moving from Outlook to Gmail who want to use Shortwave face a two-step migration (Gmail import first, then Shortwave) with no native assistance.
Verdict
Shortwave in 2026 is the clearest answer to the question “what does a Gmail client look like if you rebuild it from scratch for the AI era?” The AI is genuinely integrated, not bolted on — AI Summary, AI Search, AI Filters, and AI Write all deliver real time savings in daily use. The Gmail-only constraint and the absence of a free tier are meaningful gates that disqualify it for a portion of the market. For Gmail-native teams and professionals who want to automate the actual email work, it is the best option currently available.
Best for: Gmail-only professionals and teams who process high email volume and want AI to handle triage, search, summarization, and drafting — not just suggest it. Inbox by Gmail veterans who want the Bundles + calm-inbox ethos with a full AI layer on top.
Skip if: You need Outlook, IMAP, or Exchange. You want a free tier. You prioritize keyboard speed over AI depth (Superhuman is sharper there). You need email encryption.
Worth Business ($24/mo)? Yes, for Gmail-heavy teams where the collaboration features (email assignment, shared labels, team prompts) and AI Search justify the per-seat cost. For a solo user, Premier at $36 adds enough AI depth to be the right step up from Business.
Worth Max ($100/mo)? For power users who need the highest AI request volume and the expert model tier — yes. For most, Premier is the sweet spot.

Frequently asked questions
Is Shortwave free?
As of 2026, Shortwave does not offer a permanent free tier. All plans start with a 14-day free trial, after which you must choose a paid plan: Business at $24/month/seat, Premier at $36/month/seat, or Max at $100/month/seat — all billed annually. There is no stripped-down free option for solo Gmail users. If you need a free Gmail client, Gmail on the web or Spark’s free tier are the practical alternatives.
Is Shortwave Gmail-only?
Yes. Shortwave is Gmail-only by design — it connects exclusively via the Gmail API and does not support Outlook, IMAP, Exchange, Yahoo, or iCloud. This is a deliberate architectural choice: the Gmail API lets Shortwave read labels, threads, and send-as aliases natively, and powers its AI Search across your full Gmail history. If you have any non-Gmail account you need in the same client, Shortwave is a hard stop.
What platforms does Shortwave support?
Shortwave runs on iOS, Android, Mac, Windows, and web. This makes it one of the few AI-first Gmail clients with genuine cross-platform parity — Mimestream is Mac/iOS only, and Superhuman lacks a native Android app as of early 2026. The Windows desktop app launched after Android (August 2023), completing the cross-platform picture.
Who founded Shortwave?
Shortwave was founded by Andrew Lee and Jonny Dimond, both former Google engineers who worked on Google Inbox — the beloved Gmail client Google shut down in 2019. Lee serves as CEO. The company is backed by Union Square Ventures (USV) and Lightspeed Venture Partners and is headquartered in San Francisco.
How does Shortwave AI Search work?
Shortwave’s AI Search goes beyond standard Gmail search by understanding natural language queries — you can ask “find the email where Marcus mentioned the Q3 budget” and it retrieves the thread rather than requiring keyword syntax. On the Business plan, search covers 5 years of history with up to 50 threads per query. Premier extends to unlimited history and 100 threads per query. The AI indexes Gmail labels and attachment content, not just subject lines.
How does Shortwave compare to Superhuman?
Both are paid-only AI Gmail clients aimed at productivity-focused users. Superhuman is more focused on keyboard-first speed, split-inbox read receipts, and its Inbox Zero methodology — pricing starts around $30/month. Shortwave is AI-heavier (bundles, AI filters, AI Search, MCP integrations) and has broader platform support including Android and Windows. Superhuman is better for solo speed-triagers; Shortwave is better for teams needing AI automation and collaboration features like thread sharing and email assignment.
